Title: Vertical compensator for bernoulli pick-up head
Inventor: PAPILLON JEAN-MARC
IPC: B66C1/02
Filed: 2001-05-15
Abstract: There are many industrial applications in which it is desired to pick up an object without contacting the object and without damaging the object by any mechanical means such as suction devices, fingers, prongs, tweezers or the like. Although the use of such pick-up devices are known, there are situations for which the presently known systems are not suitable which include those dealing with relatively small parts or having to operate in relatively small spaces. The use of the Bernoulli principle in lifting and positioning components, particularly components having a flat surface, it well known. The present invention relates to a device for picking up objects by utilizing a flow of gas, such as air, permitting self-adjustment of the height position of the device with respect to the object and permitting vertical movement of the device with the object attracted thereto.

Title: Device for supplying seal air to bearing boxes of a gas turbine engine
Inventor: FUKUTANI MASAYUKI
IPC: F01D25/12
Filed: 2001-05-30
Abstract: Provided is a device for supplying seal air to the bearings of a gas turbine engine which allows the seal pressure to be kept even between the front and rear gear boxes without complicating the passages for supplying the seal air to the bearing boxes. Sealing air drawn from a part of high pressure compressor is conducted through passages defined between the inner periphery of the rotors of the high pressure compressor and a high pressure turbine and the outer periphery of the outer shaft, and is distributed to the front and rear bearing boxes. By appropriately providing narrowed parts in these passages, seal air is evenly distributed between the front and rear bearing boxes. Thus, even in case of a failure of one of the oil seals, any concentrated leakage of the lubricating oil can be avoided.

Abstract: The present invention provides for a tool (e.g. a method and system and related embodiments) for automatically generating display formatting instructions (i.e. markup code) for an unformatted document. Controls defining display formatting instructions are used to generate the formatting instructions for the unformatted document. A reference to the controls and t he unformatted document in the formatted document allows formatting instructions for the unformatted document to be generated. Formatting instructions for the unformatted document may optionally be incorporated into the formatted document for display therewith. This allows sources of content for a web page to be separated from the web page and provides quick, automatic updating of the web page in response to a change in the sources. The controls of the present invention can be imbedded in each other, allowing complex web pages to be easily created.

Abstract: A Venetian blind cutting machine comprises a mold assembly, which has a main block and a guiding slot on the main block. A sliding block slidably receives in the guiding slot. The guiding slot has at least one stopping potion for stopping the sliding block. The sliding slot is for receiving slats therein between a closed end of the guiding slot and the sliding block. A cutter is slidably provided at the main block of the mold assembly for free shifting. Two driving bars have ends thereof fastening to the cutter. A joint block has two openings for receiving the driving bars therein and holding the driving bar therein by friction. The joint block is fastened to the sliding block. Whereby, the driving bar will drive the cutter, the joint block and the sliding block to move along with it. The sliding block will press the slats first to lock the slats in the guiding slot automatically. While the joint block has been pressing the slats, the driving force of the driving bar will overcome the friction of the joint block. Thus, the joint block will loose the driving bar and the driving bar will move continually and drive the cutter to cut the slats.

Patent CA-2390622-A1 (CA)
Inventor: MIYAZAKI TOSHIHISA
IPC: B60K1/04
Filed: 2002-06-13
Abstract: A battery is mounted to a front part of a wheel house/damper housing, and a relay box as automotive equipment is mounted to the rear of the battery via front and rear stays in such a manner as to be separated upwardly. A guide surface is formed at a front end of a lower side of the relay box, and a corner at a rear end of the battery is made to face the guide surface. When the battery is moved rearward in a vehicle collision, the relay box is moved upwardly by a load transmitted thereto from the battery via the guide surface to thereby be separated from the vehicle body. Accordingly, the impact absorbing performance can be increased by preventing the disturbance of the relay box to the rear movement of the battery, and damage to the relay box can be suppressed to a minimum level.
